[Clinical and radiographic factors associated with failure of the dynamic hip screw system].

Background: The most widely used fixation system for transtrochanteric fractures is the dynamic hip screw system, which has a failure prevalence of 10 to 17% and it is associated with the presence of clinical and radiographic factors.

Objective: To evaluate the association of clinical and radiographic factors with the failure of the screw system in post-operative patients for transtrochanteric hip fracture.

Material Y Methods: A case-control study was carried out.
